JP1 Remotes

Mark Pierson · Posted: Wed Feb 27, 2013 8:51 pm Post subject: Comcast URC-1067CBC4

This old timer needs help! Embarassed

Just got a new Comcast DVR and it came with a URC-1067CBC4 remote. It has the red OK/Select button and a JP1 header installed. I can't be sure but it looks like the PCB is marked JP1 just below the header.

Anyway, I fired up RMIR and tried to download but get "No RDF matches signature starting 2556". I did a raw download and need some assistance on what to do next.

Is this a new remote in need of a new RDF or am I that far out of touch with JP1 that I don't remember anything?

Well, as the old saw goes, you "probably have forgotten more about JP1 than most people will ever know", but that doesn't mean you're out of touch!

Anyway, we've seen this remote once before, but didn't get far enough to have an RDF. Please do check the signature via 983 to make sure we're talking about the same remote.

It is a JP2 remote (I think), and you'll need RMIR 2.02a to talk to it. JP2 remotes use the Maxim MAXQ610 micro, and we have had success using FTDI and transistor interfaces with them. Interfaces using the Prolific chipset (e.g. DIY Gadget) have been problematic.

Anyway we need to get a Raw Download, and macro/keymoves to find out the button numbers.

I would be interested in assisting here. If someone would like a remote to work on, I'd be willing to donate.

I have a remote, and am thinking of picking up several more.

Do you have a JP1.3 flash cable? Can you use RMIR to do a raw download? If so, then we can work together to get a functioning RDF.

I do and can confirm that I am able to pull in raw data. I'll post the file this morning, but I think it is the same as the one linked above.

The remote is ~$6 on eBay with free shipping brand new. I'd be more than happy to send you one or PayPal you the money if you're interested. Send me a PM.

Thanks for the help

Yes, that Raw download looks fine. Would you mind posting a link to the eBay listing?

Speaking from experience with the Atlas 1056B03 (JP2) versus 1056B01 (JP1.3), eBay vendors are generally not aware of significant differences between remotes which are cosmetically very similar. I recommend directly contacting the seller to make sure that they will ship a BC4 rather than a BX3/BC3, if the buyer wants a JP2 remote.

Here's a candidate RDF file which has been tested for basic functionality by bcjenkins.
He has also opened the case. The PCB says UEI Insight 3 device remote, URC-2067BC4 rev 0, Sept 2011. However, Comcast seems to refer to this as a 1067 rather than a 2067.
